Miniature rose plant named `Meidonfe`

ABSTRACT

A new and distinct variety of rose plant of the miniature class is provided which abundantly forms attractive double red flowers. A bushy growth habit is exhibited. The plant propagates well from cuttings. The blossoms possess no fragrance. The plant can be grown as attractive ornamentation in the landscape or as a decorative pot plant.

SUMMARY OF THE INVENTION

The new variety of miniature rose plant was created by artificialpollination wherein two parents were crossed which previously had beenstudied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the product of the pollination of the `Meijikatar` varietyU. S. Plant Pat. No. 4,682) and the `Meirutral` variety (U. S. PlantPat. No. 7,021). The male parent (i.e., the pollen parent) of the newvariety was the `Ruimired` variety (U. S. Plant Pat. No. 5,770). Theparentage of the new variety can be summarized as follows:

    (`Meijkatar`×`Meirutral`)×`Ruimired`.

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of miniature rose plant of the presentinvention possesses the following combination of characteristics:

(a) forms in abundance attractive double red flowers,

(b) exhibits a bushy growth habit,

(c) propagates well on its own roots, and

(d) is particularly suited for growing as an ornamental pot plant.

The new variety well meets the needs of the horticultural industry. Itis particularly well-suited for use as attractive ornamentation in thelandscape or for growing as a decorative pot plant.

The new variety has been found to undergo asexual propagation in Franceby a number of routes, including budding, grafting, and cuttage. Asexualpropagation by the above-mentioned methods as performed in France hasshown that the characteristics of the new variety are strictlytransmissible from one generation to another.

The new variety has been named the `Meidonfe` variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were one year of age and were observed during Aprilwhile growing on their own roots indoors at LeCannet des Maures, Var,France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The terminology whichprecedes reference to the chart has been added to indicate thecorresponding colors in more common terms. The description is based onone year-old specimens of the new variety which were observed duringApril while growing on their own roots indoors at LeCannet des Maures,Var, France.
